Hi Devs,
I am trying to implement a CRUD app(modeling blogs) using Django & DRF. I
am using *rest_framework.serializers.ModelSerializer* for serializing my
model. While sending a POST, PUT request the serializer is not saving my
data, what am I missing?
*terminal*
> Request data:- {'title': 'title 2', 'body': 'body 2'}
> Serialized data:- {'pk': 2, 'title': '', 'body': ''}
> [06/Feb/2020 17:19:36] "POST /api/blog/ HTTP/1.1" 201 29
> [06/Feb/2020 17:19:44] "GET /api/blog/ HTTP/1.1" 200 168
*views.py*
> from blog.models import Blog
> from blog.serializers import BlogSerializer
> from django.core.paginator import EmptyPage, PageNotAnInteger, Paginator
> from rest_framework import status
> from rest_framework.decorators import api_view
> from rest_framework.response import Response
>
>
> @api_view(["GET", "POST"])
> def blog_collection(request):
> """
> API for operations on blogs, handles following operations
> 1. Fetch(GET) the list of blogs.
> 2. Create(POST) a new blog entry.
> """
> if request.method == "POST":
> print(f"Request data:- {request.data}")
> if request.data == dict():
> return Response(status=status.HTTP_400_BAD_REQUEST)
>
> serializer = BlogSerializer(data=request.data)
>
> if serializer.is_valid():
> serializer.save()
> print(f"Serialized data:- {serializer.data}")
> return Response(serializer.data, status=status.HTTP_201_CREATED)
>
> return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
>
*serializers.py*
> from blog.models import Blog
